It doesn't really make a difference, but you can just use "csup" now instead of installing "cvsup". csup is part of the FreeBSD base.

You can just do # cd /usr/src && make cleanworld

From the error, it looks like you're missing "flex". Maybe check your PATH? It should be in /usr/bin/flex. It is part of the base system. If it's not there, you could try installing flex from the port (textproc/flex).

I would suggest trying a different cvsup server and updating again. If that fails I would try removing the entire source tree (remember to save your kernel configs, etc.), then checkout a fresh source tree.
